...MAY WAS WETTER AND COOLER THAN NORMAL IN NORFOLK...

FROM RECORD BREAKING COLD TO RECORD BREAKING HEAT MAY HAS BEEN QUITE THE MONTH.
THE MONTH BEGAN COLD, TEMPERATURES WERE 10 TO 17 DEGREES BELOW NORMAL FOR THE
FIRST WEEK. IT WAS DURING THIS TIME THAT WE ALSO HAD RECORD LATE SEASON SNOWFALL
ACROSS NORTHEAST NEBRASKA. THIS COLD SNAP DIDN`T LAST LONG. BY THE END OF THE
SECOND WEEK WE HIT 103 DEGREES, WHICH BROKE A NEAR 100 YEAR OLD RECORD. AFTER
THE HEAT WAS OVER THE RAINS BEGAN, WITH SEVERAL INCHES OF MUCH NEEDED RAIN
FALLING. THIS ABOVE NORMAL RAINFALL MEANS WE`VE NOW HAD TWO STRAIGHT MONTHS OF
ABOVE NORMAL PRECIPITATION IN NORFOLK.

THE AVERAGE TEMPERATURE OF 59.4 DEGREES WAS 1.1 DEGREES BELOW NORMAL
AND THE 48TH COLDEST FOR THE 112 YEARS OF RECORD AT NORFOLK.  THE TOTAL
MONTHLY PRECIPITATION OF 5.40 INCHES WAS 1.47 INCHES ABOVE NORMAL AND THE
25TH WETTEST ON RECORD.  THE TOTAL MONTHLY SNOWFALL WAS A TRACE.

DAILY RECORDS SET IN MAY 2013:
DATE        RECORD         READING  PREVIOUS RECORD
MAY 12      LO TEMP          29       30 (1946)
MAY 14      HI TEMP         103       96 (1915/1941)
